Pincer clamp

The present invention relates to a pincer clamp having an articulation, which has two clamp arms mutually connected by the articulation. The clamp arms are divided into a hand lever segment, a transition segment, and a head segment having the clamping jaw plate. The second clamping jaw plate protrudes laterally with respect to the adjacent transition segment. The other first clamping jaw plate has an included angle of about 35 DEG~ 55 DEG with respect to the adjacent transition segment. The S-shaped inner outline of the clamping jaw plate has a sawtooth outline attached with teeth in the case of constituting the bite. The bite is a parallelogram when the tips of clamping jaw plate contact each other. The longer inner outline of the bite is constituted by the sawtooth outline with the teeth whose cross sections have the unequal-length side surfaces. The shorter inner outline of the bite and the inner outline of the tip of the clamping jaw plate are constituted by the sawtooth outline with the teeth whose cross
